2 Claims. (Cl. 30`-72) This invention relates to new and usefulimprovements in a four sided safety razor and blade.

The invention has for an object the construction of an article asmentioned which is characterized by a four sided head piece with acentral threaded-stud and several spaced pegs, a four sided razorbeneath said head piece, a four sided guard beneath the razor, and ahandle threadedly engaging said stud to hold the head piece, blade andguard together.

More particularly, the invention has specific reference to a novelarrangement of the pegs and complementary receiving openings in therazor blade.

Still further the invention contemplates arranging the pegs in astraight line with the central threaded stud, and arranging the openingsin the razor in the form of a cross so that the razor may be engaged onsaid stud and pegs in several adjusted positions.

Still further the invention'proposes a construction whereby each of theedges of the four sided blade is supported upon the head piece and guardin a reinforced condition.

Furthermore, the invention has for an object the association with thehead-piece of a means for holding any one of the sides in reinforcedposition to enhance the efficiency of the blade during shaving.

Another object of the invention is the construction of a device asdescribed which is simple and durable and which may be manufactured andsold at a reasonable cost.

For further comprehension of the invention, and of the objectsandadvantages thereof, reference will be had to the following descriptionand accompanying drawing and to the appended claims in which the Variousnovel features of the 'invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosurez-Fig. 1 is a .plan view'of an article constructed according to thisinvention.

Fig. 2 is a fragmentary sectional View taken on the line 2 2 of Fig. 1.

Fig. 3 is a perspective View of thelblade per se.

Fig. 4 is a plan view of a guard per se of a razor according to anotherembodiment of the invention.

Fig. 5 is a perspective view of a modified form of blade to be used withthe razor partially shown in Fig. 4.

Fig. 6 is -an edge elevational view of Fig. 5.

Fig. 7 is a fragmentary vertical sectional View of the complete razor,this view being taken on of the blade is reinforced.

a section line which would pass through the line 1--1 of Fig. 4.

Fig. 8 is a view similar to Fig. 7 illustrating another modification.

Fig. 9 is a plan view of the razor shown in 5 rig. s.

which the pegs and the stud pass. A handle I8 l5 is threadedly engagedon the central threaded stud II and tightly screwed therein for holdingthe head piece, the blade and the guard together in a unit. s

The head piecel Ill and the guard I 5 are 20 formed in curved quadrantswhich are adapted to curve the blade into four sections radiating fromthe center thereof so that each of theedges In Fig. 2 it should be notedthat both the guard and the head piece are curved. This represents thecurvature of two of the quadrants diametrically opposite each other.From Fig. 1, the quadrants may be noticed between the diagonally crossedlines indicated by the reference numerals 20. The blade I3 has cutoutcorners I3'L so that each of the edges thereof are free and may exindependently. The opening I4 is substantially in the form of twoldiagonally crossed arms I IIa and I4". s At the junction of these armsthere is suflicient space for the threaded stud II to pass. The pegs I2may pass through either of -the ends of the arms I4a and I4b. Thispermits the blade I3 to be Aset into position upon the razor in severaldifferent ways. It may be set with one face adjacent the head piece orthe other face adjacent the head piece.

In addition, it may be turned to several different positions.

In Figs. 4-7 inclusive a modified form of the 45 article is disclosedwhich distinguishes from the prior form in several details. Moreparticularly,l

an opening I 4' consisting of branches I 4aa and I4bb parallel to thesides of the razor. The diagonals of the blade are formed with narrowslots 22 so as to reduce the amount of metal at these 55 areas to renderthe blade more exible. This is of value in that it then may be readilyplaced into the position controlled by the curvatures of the head pieceand the guard.

In other respects this form of the invention is identical to theprevious form and similar parts may be recognized by the same referencenumerals.

In Figs. 8 and 9 a still further modied form of the invention isdisclosed in which provision is made for forcing one or more of theedges of the razor ends into curved shape to stiffen the razor asdesired. More particularly, in this form there is a fiat head piece i0which has the stud Il projecting from its center. This ilat' head piececooperates with the curved guard l5. The guard l5 is curved in quadrantsas indicated by the oblique lines 20 in Fig. 9. 'Ihe blade I2, whenplaced in the razor, normally would have all of its edges free since theparts may only be clamped tight at, the center. Then, any one of thefour sides of the razor may be placed into operative condition byscrewing down the threaded elements 25 threadedly engaged through the Yhead piece. These threaded elements are arranged in pairs for each ofthe quadrants. As shown in Fig. 8, the left hand side of the razor bladeis forced into the curved position and is thus ready for use. 4 Theother sides of the razor blade are free. The purpose of the arrangementis to only ilex that edge of the blade which is to be used so as tostiffen it and make it perform emciently, while the other edges are freeto prevent undue stresses being placed upon the blade which willinterfere with the proper flexing of the edge which is used. It shouldbe understood that if the blade is tightly held on the four sides itwill not be as flexible if it is held tightly upon one side.

While I have illustrated and described the preferred embodiment of myinvention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by United States Letters Patent isz- 1. A four sided safety razorand blade, comprising a four sided head piece with a central threadedstud and several pegs, a four sided razor blade .beneath said head pieceand having openings through which said stud or pegs pass, a four sidedguard beneath said razor blade and having openings into which said studand pegs pass, and a handle threadedly engaging said stud and holdingsaid head piece, blade and guard together, said head piece being fiat,said guard being convexed, and m'eans on the head piece and engageableagainst the sides of the blade selec- 20 tively to conform any of thesides of the blade to the shape of the guard.

2. A four sided safety razor and blade, comprisingA a four sided headpiece with a central threaded stud and several pegs, a four sided razorblade beneath said head piece and having openings through which saidstud or pegs pass, a four sided guard beneath said razor blade andhaving openings into which said stud and pegs pass, and a handlethreadedly engaging said stud and holding said head piece, blade andguard together, said head piece being flat, said guard' being convexed,and means on the head piece and engageable against the sides of theblade selectively to conform any of the sides of the blade to the shapeof the guard. comprising elements threadedly engaging through said headpiece and engaging the top portion of said blade for shaping the saidblade.
